EFICE JOHN JACKSQN, OF CHICAGO, ILLINOIS.

BOOK-MARKER.

Specification of Letters Patent.

Patented May 10, 1910.

Application filed January 7, 1910. Serial No. 536,883.

T 0 all whom it may concern:

Be it known that I, JOHN JACKSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Book-Markers, of which the following is a specification.

My invent-ion relates to book markers, and has for its object to produce a marker which will not only indicate the page to which it is desired that future reference be made but also the line, and even the particular word where the reader left off.

It frequently happens that a lawyer in making an argument in court wishes to read extracts from various books, and itis desirable that he should be able to turn directly to the exact word where his quotation is to commence. It is the object of my invention to render this possible and the object is accomplished by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view showing a book having my marker in position thereon, and Fig. 2 is a longitudinal sectional view of the marker.

Similar letters refer to similar parts in the two views.

A clip is formed preferably of a comparatively stiff plate a having a tongue I) struck up therefrom, the two parts being adapted to take the edge of a leaf between them and hold the marker firmly in position. To this clip are attached one or more arms 0, the outer arm bearing at its extremity a pointer (Z. The parts are all articulately connected preferably by means of the eyelets e. The joints are so constructed that they will per mit the parts to be moved to different positions but will tend to hold the parts in the position to which they are moved, this being accomplished in the present device by the friction set up by the rimmed over edges of the eyelets.

In the preferred form of my device the end member (Z is connected at a point between its extremities, and for convenience it is desirable that said end member be shaped in the form of an arrow or other conventional pointer.

In operation, when the user desires to mark a particular point on a page he slips the clip over the page in the manner shown in Fig. 1 and then moves the point of the member (Z to the exact spot on the page to which reference is to be made. The book may then be closed up and handled in the ordinary way without disturbing the device, and when reference to the book is again to be made the proper point may instantly be found, for the clip a, b, which projects beyond the edge of the page, will indicate what page is wanted and the pointer 0? will indicate the particular spot required.

It will be understood that a marker of this character may be made to occupy but little space between the leaves of a book, the thickness in Fig. 2 being exaggerated in order to clearly indicate the construction.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is A book marker comprising a clip consisting of a sheet of comparatively stiff material having a tongue struck up therefrom, and three arms articulately joined together, one of them being articulately joined to said clip, the joints affording sufficient friction to hold the parts in the position to which they are set, and the arm most remote from the clip being attached substantially midway between its ends and having the form of a pointer.

In witness whereof, I have hereunto subscribed my name in the presence of two witnesses.
